This is a great phone, feel good in the hand, the fingerprint reader is really snappy and the screen is good! Cyanogenmod works fine and the battery life is very good (so far). The OnePlus Two feels slightly more high end, but is also more expensive. And as you're probably going to put a case anyway, it doesn't matter too much. In terms of speed, games run well and without hiccups.

I can really recommend this one, if you're looking for a high value phone at a low price.

ive had this phone for 14 days, during them 14 days you get what you expect. its simply amazing for its price tag.

pros:
battery is great
camera is average
screen is amazing
handles heavy usage apps with ease
havnt experienced any lag yet
has nice extra settimgs for more customizable use
audio fx helps with the sound
fast charging + usb 3.0 is really good

cons :
personally had a major battery problem with random reboots and dropped it one from 1feet accidently, pretty much killed the phone, battery malfunctioned, went 50% to 1% in a second, then charging stopped too.

phone is really fragile, especially the plastic back, you can literally push into it to feel the inside.

camera doesnt perfom at 30fps with its stock camera, google camera does the job tho which is just a software problem i guess.

advice, i would definitely recommend this phone to almost anyone, however you seriously need a good case for this phone, not fpr the clumsy and safe ocd people like me need to be careful too, its just too fragile.but seriously is worth the money spent on it.

wish leonovo would use motorolas durability on this phone. considering they own motorola too

I got my ZUK Z1 about a week ago, it's a amazing device. My previous phone is a Samsung S5, and to be honest, the only thing i miss is the sd card slot, of course the 64gb is far more than i need but it's easy to handle a sd card.

I'm stuck with ZUI and i do not intend to change, it's pretty cool and i like it very much. The U-touch function it's really usefull.

I just tested the call quality, amazing sound volume, i'm quite satisfied! Fingerprint Scanner is the best i have ever tested, i'm completely impressed. Screen is amazing as well.

The only thing so far that bothers me is that it doesn't support my native language (portuguese), so when typing it will only give me suggestion for english words, what i'm doing is adding portuguese words on it xD

*There's a system update 1.2.040 avaliable but i haven't updated yet, system is perfect and i see no need for it lol

Bought one and no problem with it so far on T-Mobile US, in my area (Northeast US)
I noticed my HSPA+ and LTE speeds are capped to 7~9Mbps. Which is enough for most things on a phone, like spotify, netflix...

Snapdragon 801 is one of the best chips that came out with good support for anything, 805 definitely better by a small margin, but I think it would come at a higher price range like Nexus 6 for $350~$400

for the price of $300, the other contender is definitely Zenfone 2, but it doesn't have fingerprint scanner unfortunately!

when I tested on my zenfone 2 I could get 30~50Mbps readings from other areas, so if zuk z2 gets US band, it would be amazing :D I'll def buy one.
